The Lights singer, who recently split from DJ boyfriend Skrillex, was at the launch to support friends Anne Hathaway and Amanda Seyfried, but she stole the show when she arrived wearing a white sheer gown with no bra, exposing her nipples.

Goulding, whose dark underwear could also visible, appeared not to mind the extra attention and she smiled confidently for the cameras as she mingled at the event.

The 25-year-old isn't the only celebrity to reveal a little too much for the cameras - reality star Khloe Kardashian's pert nipples were on show when she debuted as the co-host of US show The X Factor last month, and actress Emma Watson exposed a silicone pastie covering her modesty during the Los Angeles premiere of The Perks of Being a Wallflower.
